Application filed September 18, 1922., Serial so. assess.

To all whom it may concern: h

Be it known that I, THOMAS SEVERSON, a citizen of the United States, residing at Duluth, in the county of St. Louis and State of Minnesota, have invented certain new and useful Improvements in Bunghole Spuds, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to bunghole spuds for metal receptacles such as oil barrels,

drums, or the like, and the principal object of same is to provide a more practical and efiicient spud t an heretofore known;

Other objects and advantages of the peculiar structure will appear in the further description of the invention.

Referring to the accompanying drawing forming, part of this application in which like reference characters indicate like parts:

Figure 1 is a' lan portion of a meta c or barrel illustratinga %lug and spud within same, and;

igure 2 is a central vertical section on the line 2-2 Figure 1." j

1 represents the shell or Skll'l of a metal receptacle, such as a drum or barrel, the r m of the bunghole of which is pressed outwardly' referably in polygonal form, as at 2, such form being particularly for the purpose of preventing the possibility of rotation of the plug 3 when incorporated therewith.

The plug is of predetermined thickness so as to snugly fit within the countersink of the rim 2 with its inner face flush with the inner face of the skin of the container, and the annular bead 4 about the upper peripheral edge of its inclined exterior, said. bead being for the purpose of forming an annular seat about the bunghole through the s ud when the skin of the container is force into position thereabouts and into the inclined slot view of a fragmental:

er face of the spud is provided withan 5 about the bunghole. This. seat is .for the reception of the gasket 6 under'the head 7 of the plug 8 which isscrew threaded into the spud, the plug of the ordinary it is well known tothoseversed in the art that agasket usedn nder such plugs is very apt to. become softened somewhat by the action of the contentsrofthebarrel when kerosene or gasolene is contained therein,

and under such circumstances the gasket is a tin bulge out in; places by the compression of the plug; and it is obvious that the seat formed in the manner above described will prevent such bulging and render possible the repeated use of the gasket.

The slot 5 flares downwardlyand outwardly in respect to the bunghole substantially parallel with theinclination of the outermost walls of the spud so thatwh'en the'skin or shall ofthe receptacle is forced therein a clinching eifect results which firmly secures the spud in position, as is obvious.

Having thus described my invention, what I claim and desire to secure by Letters Patent, is:

The combination with a metallic receptacle having a bunghole therein, of a s ud for same having an inclined circum erential wall and an inclined annular-slot s aced inwardly from the inclined Wall an parallel therewith, said slot being for the reception of the marginal edges of the bunghole, and an annular stepped gasket seat intermediate of the uppermost termini of the inclined walls.

In testimony whereof I hereunto atfix my signature in the presence of two witnesses.
